I've gone through that experience multiple times as well. Also over 30lbs each time. Also having kept it off for years, although not quite a decade for my longest period. COVID was my last regression, as it was for many who lost it and maintained it the way we both did.

The GLP-1's are a game changer. I will never lose weight the "white knuckle" way again. I can, and I have proven it to myself and others. It's not complicated as you say - it's quite simple.

It's simply such a giant imposition on your life and mental well being that I am thankful others won't have to go through it as their only option in the future. The sheer chunk it takes out of my executive function means I can't perform nearly as well at other tasks in life. The GLP-1 class of drugs make it trivial in comparison. Like a performance enhancer for a diet.

I also have worked out a hell of a lot more taking Tirzepatide than I ever did counting calories on a food scale. This is because I feel so much better it's not even a comparison - primarily mentally, but also physically due to the other positive side effects the drug has associated with it. Plus I don't feel guilty when I go out with friends to a burger joint - I eat half and feel perfectly satiated, no guilt or "cheat day" required. My energy levels are not comparable. I have much more time in my day available for other activities, such as keeping appointments with my personal trainer at the gym or taking 6 miles of walks per day.

Losing weight and maintaining an active healthy lifestyle doesn't have to "suck" any more.

I feel like you need someone who has gone through both experiences to actually have credibility in this conversation. Willpower isn't a special trait, it's not something to lord over other people.
